Flüssigkristall-Anzeige mit vielfachdomänen Struktur

Multi-domain type liquid crystal display

Dispositif d'affichage à cristal liquide avec structure à multi-domaines

Abstract

No rubbing treatment is done on a pair of transparent substrates. A liquid crystal layer is sandwiched between these transparent substrates to exhibit a multi-domain structure wherein liquid crystal molecules are oriented to various directions at the interface between the liquid crystal layer and a transparent substrate so that the liquid crystal molecules can be considered to be orientated at every direction at an equal possibility with respect to the directions in a plane parallel to the transparent substrate. Crossed or parallel polarizers are disposed outside the transparent substrates. An optical compensation plate having an optically negative anisotropy with an optic axis perpendicular to the plate is inserted between the pair of substrates and the pair of polarizers. The compensation plate may be replaced with optical compensation plates of positive optical anisotropy with optic axes in the plate arranged in crossed configuration.
